IPv4 universal complete RegEx with options

IPv4 universal complete RegEx with options.txt

NOTE: Each RegEx is a single line and Java users, for example, need to mind Java's additional requirements (such as escaping escape characters), otherwise they should work in every RegEx flavor.

This code ain't my work originally, I modified it.

-------------------------------------------------------------------------

No support to get the individual sections:
```
(?:[1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.(?:[1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.(?:[1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.(?:[1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])
```

With support to get each section with match groups 1-4
```
([1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.([1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.([1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.([1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])
